10 Claims.

Thisinvention relates to improvements in tools and is directed more particularly to the provision of an economical and. simple device for operatively holding a piece of paper such as sandpaper, blotting paper and the like.

It is the principal object of the invention to provide a tool which has a removable working part associated therewith in such a way that itmay be easily and securely held in place for its operating function and as readily removed and replaced with another working part.

A further object of the invention is to provide a tool of this class which is not only inexpensive to manufacture but which may be conveniently manipulated to provide a maximum scraping, polishing or blotting surface.

Various other novel features and advantages of the invention will be more fully hereinafter referred to in connection with the following description of the preferred form thereof, in which description reference is had to the accompanying drawing, wherein:

Fig. 1 is a plan view of the tool of the invention;

Fig. 2 is an end elevational view of the tool shown in Fig. l; and

Fig. 3 is an inverted plan view of parts of the tool of the invention.

Referring now to the drawing more in detail, the invention will be fully described.

A plate member 2 is provided and this is preferably formed of some substantially hard but slightly yieldable material such as sheet metal. This plate 2 consists of a substantially flat main body portion 4, opposite side portions 6 which are bent inwardly back upon the body 4 as shown, and flanges 8 which extend upwardly from the inner marginal edges of the portions 6.

According to the preferred form of the invention, the flanges 8 extend outwardly slightly in opposite directions as shown. This is for a purpose which will presently appear.

A clamping member I is provided and this also is preferably formed of a single piece of 7 sheet metal which is slightly spring-like in nature. This member ID has a central grip portion I2 which is preferably curved at its upper side as shown and has converging sides spaced apart to provide a slot 14 between their lower marginal edges.

Connecting plate portions l6 extend outwardly in opposite directions from the lower marginal edges of the sides of the grip [2 to downwardly depending flanges l8. These flanges l8 are formed to extend substantially complemental to the flanges 8 of the plate 2 and to co-operate therewith for a clamping function which will presently be described.

Disposed adjacent the outer side of the plate member 2 is a working part 20 and this may consist of a sheet of abrasive material such as sand-paper, polishing material such as felt, or absorbent material such as blotting paper or the like. In any event, it is desirable that the working part 20 be formed of some foldable 1O material.

That is to say, the main body 22 of the working part 20 is disposed flat against the outer side of the portion 4 of the plate and its side portions are bent inwardly and upwardly between the flanges 8 and I8 and has free end portions 24 extending over the upper marginal edges of the flanges 8 as shown.

It will now be noted that the clamping member l0 serves both a clamping and ripping function. That is to say, the member I0 is formed as stated of spring-like material and is provided with an intermediate slot M as shown.

It is obvious that byurging the sides of the grip portion l2 towards one another and thus tending 25 to close the slot I4, the flanges I8 would be automatically moved towards one another. It is to this end that I provide a cam lock device as shown in Fig. 3. p

This cam lock device consists of a plate member 26 having a main body part 28 and a handle or operating member 30 extending therefrom. Eccentric slots 32 are provided in the part 28 as shown.

Rigidly associated with the grip ID are lugs 34. 35 Preferably one lug 34 is provided in each connecting portion l6 of the member l0 adjacent the slot l4. The lugs 34 extend through the slots 32 and by means of the member 30 the plate 26 may be moved into and out of locking position.

When in locking position, the lugs 34 are relatively close together so that the flanges l8 are pulled inwardly toclamp the member 28 against the flanges 8. When in unlocking position, the spring-like clamping member ID allows the part 28 to be removed from its support 2. Thus a new part 20 may be folded about the support and clamped thereto.

It may be seen that the marginal edge portions of the part 20 are retained between the upstanding and downwardly depending flanges 8 and I8 respectively. That is to say, by urging the outer flanges l8 inwardly towards one another they are 55 caused to bear against the part 20 and urge the inner flanges 8 inwardly.

It is a further feature of this invention that the urging of the integral flanges 8 inwardly causes the plate portion 4 to become curved so that its outer surface is slightly convex. Thus, when the tool is operated, the pressure given by the operator to the central grip portion l2 tends to flatten the surface out sothat the whole working surface of the part 20 is in contact with the surface being worked upon.

While I have described my invention in great detail and with respect to a preferred embodiment thereof, 1 do not desire to be limited to such detail or embodiment since many changes and modifications may be made without departing from the spirit and scope of the invention in its broader aspects. Hence, what I desire to claim as new and secure by Letters Patent of the United States is:

1. A tool of the class described comprising in combination, a supporting member including a plate portion and upstanding flanges spaced inwardly from opposite marginal edges thereof for a member of foldable material having a main body portion disposed adjacent said plate portion and opposite side portions extending over said flanges, and releasable means for clamping said foldable member to said supporting member including a central grip portion and outer downwardly extending flanges for lying adjacent the opposite side portions of said member outside said upstanding flanges.

2. A tool of the class described comprising in combination, a supporting member including a plate portion and upstanding flanges spaced inwardly from opposite marginal edges thereof for a member of foldable material having a main body portion disposed adjacent the outside of said plate portion and opposite side portions disposed adjacent the outside of said flanges, a clamping member of spring-like material for clamping said foldable member to said supporting member including a central grip portion and outer downwardly depending flanges for lying adjacent the outside of said side portions of the foldable member, and means for urging said downwardly depending flanges towards one another.

3. A tool of the class described comprising in combination, a supporting member including a plate portion and upstanding flanges at opposite marginal edges thereof, a spring-like clamping member including an intermediate grip portion and outer downwardly extending flanges disposed outside said upstanding flanges, and releasable means for urging said downwardly depending flanges inwardly towards one another.

4. A tool of the class described comprising in combination, a supporting member including a plate portion and upstanding flanges spaced inwardly from opposite marginal edges thereof, a spring-like clamping member including an intermediate grip portion and outer downwardly extending flanges disposed outside said upstanding flanges, and releasable means for urging said downwardly depending flanges inwardly towards one another, the said upstanding and downwardly depending flanges being angularly disposed complementally to one another.
